OpenXR

OpenXR is a royalty-free, open standard that provides high-performance access to XR platforms and devices. Epic Games is one of the founding members of the OpenXR Working Group along with the Khronos Group and industry partners. This multi-company group is working to solve XR fragmentation with a cross-platform standard. With OpenXR, you can create an immersive experience in Unreal Engine that can run on any system that supports the OpenXR APIs.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
